may cause or lead to the release of wastes to the environment, a threat to human health, or a
nuisance. The Permittee shall maintain an inspection log or summary including at least the
date and time of inspection, observations made, and any maintenance, repairs, or corrective
actions taken by the Permittee. This log of inspections shall be maintained by the Permittee
